METHOD OF AND TRANSMITTING DEVICE FOR TRANSMITTING A DATA BLOCK

摘要

A method of transmits a data block of a type from a transmitting device (for example a transmitting network node) to a receiving device (for example a receiving network node), in particular during a temporary block flow. A transmitting device is capable of receiving at least two different types of positive/negative acknowledgements for data blocks of said type from said receiving device and the reaction of the transmitting device to the positive/negative acknowledgements depends on the type of the said received positive/negative acknowledgement.
